Does anyone know anything about this exhaust or more importantly have it? Even though it probably doesnt sound as great as the Apexi N1, the 40lb weight savings is hard to look away from for the under $500 price tag. Anyone know how good the power gains are? Worth the dough or stick with the N1?

 

While I ahve never heard this exhaust personally, I have heard good things about it. If you like the N1 you will prob like the corksport. Also, the power gains should be similar to the N1 I believe. I'm sure evileagle will chime in soon.

 

Under $500 and 40lbs less than steel? Is that cat-back or the whole thing all the way from the engine?

 

I just checked out the site, and it is a 40 lb. drop in weight from stock. You arent saving nearly that much weight over the N1.

 

So the N1 is actually close to the weight of the CS Ti?

 

I'm sure the CS Ti is lighter, just not 40 lbs lighter. Maybe someone else can chime in with a concrete figure.

 

Dude, are you guys serious? Only the muffler is titanium if that, maybe only the tip

 

Yes, the canister/tip is titanium and the piping is SS. The point of my question was if it sounded/performed as well as the savings in weight would qualify it as a good purchase. My goal is to keep it as bearable as possible for daily street use while still using it for my regular mountain driving abuse...

 

what is the rest of your exhaust like?

 

RB Header, Bonez resonated midpipe. Its on my project 87 SE. Its the NA motor in it right now, but i have a spare 13B sitting around and pretty soon Ill be swapping a TII in it.

 

Your setup would be loud, with the resonated midpipe it wouldn't be unbareable, but it would be loud still.

The piping is stainless and then entire can is Ti. The catback weighs 40lbs less than the stock dual catback.

As far as quality goes, not to toot our own horn, but we're right there with Apexi. Granted we don't quite have the huge name recognition that they do. But it's not like ours is something you would have to "settle" for.

 

Loudness isnt a problem for me. And its not so much as settling is that sometimes for a price like that you have to wonder what kind of quality it is even though knowing that name brands have some price inflation for their higher performance products.

You think that going with a resonator/high flow midpipe setup would help sound wise, but would it hurt my performance?

 

In terms of quality, all the pictures I have seen make the corksport system look like a generic eBay canister. Maybe you guys should add a little flare or style to the can so it isn't so boring? ...and I am not talking about lights or wild etchings. Just looking at an Apex'i muffler I can tell it looks like some extra effort was put into it.

That is the only thing that keeps me from buying it. If I can look at someones car and have to speculate whether that exhaust is a eBay fart can or possibly a well-known brand name company, then I can not consider that exhaust.

I just like something that looks like it has some extra attention to perfect the design. Maybe that is what seperates the price difference of a Corksport exhaust and a Brand-Name (HKS, Apex'i, Greddy, etc.) exhaust. You guys seems to provide the cheapest method of making an exhaust system that is reliable. But maybe that is the only market you are targeting, and therefore I can't disagree. But if you were to target my market, you'd design something that goes a bit beyond raw designs.

Of course these are my opinions, and I just now realized just how much I wrote. But I had to pass time till my next class so... maybe they will help.

 

Ahh SSAC, the bane of my existance. I get this one all day long. Us and SSAC (SSAutcoChrome) go back a ways. Long story short, their stuff is a direct knockoff of ours and they pimp their stuff all over ebay, thus making us look worse. A lot of times people get it backwards and accuse us of just ripping off SSAC, which while incredibly insulting, is incorrect as well.

Now as far as the design goes, it's not that we make it as cheap as possible, it's just that we don't mark it up like the rest. I can assure you that it costs Apexi, Greddy, HKS, Tanabe, 5Zigen, etc. even less to make this stuff than it costs us. In terms of big names here in this side of the ocean, take Racing Beat for example. Now I'm not saying their stuff isn't nice, but at the same time I'm not saying that theirs is the best or the right way to do it. We definitely cater to different audiences.

What we here feel that we are offering is the best possible product with the best possible performance at the lowest possible price that still allows us to pay the bills. If running a straight pipe with no muffler is the best way to decrease restriction, then so be it. Go grab yourself a Borla XR-1. I highly reccomend them and they work fantastically.


At the end of the day, it's all about preference and style. People have different tastes.

Personally? I run our 80mm straight through turbo back every day and I love every second of it.

 

With a header and resonated midpipe this would be STUPIDLY loud and bad sounding.

I rode in ScrapFC's NA when it had Mind train header to Bonez highflow cat to Corksport catback.

It was VERY loud, raspy and had such bad resonance it got the whole car to rattling terribly.

Oh, and I like loud! I had the JIC Spec 90 3 1/2" turbo back (with its one muffler in the whole system) and I thought it sounded great - especially with a helmet and ear plugs in . The turbo cars have a nice mellow low tone the NAs don't because after the turbo there is no exhaust pulses and the NAs have very strong pulses all the way through.

He put my stock TII catback on and it lost a tiny bit off the top as compared to Corksport; but the TII stock catback had more on top than the Corksport with the tip silencer in.

The light weight IS an attractive attribute to the thinwall stainless singles though- no denying that!

If you start to add Borlas the price soars to the cost of a quiet dual set-up as a muffler that can stand up to the NA rotary as a premuffler will cost ~$200 each. And it will start to get as heavy as a quiet dual..

 

Including the perforated centre tube? Or just the outer can?

According to your website the weight saving from the titanium muffler is only 4lb. IMO you'd have to be nuts to buy a system with titanium muffler to save weight, particularly when it costs an extra $200. $50/lb is damn expensive weight reduction!

Out of curiosity, what is it about the RB systems that you think could be improved? Other than cost obviously...

 

Perforated centre tube is steel, you caught me. But thanks for getting technical :P

The Ti setup is 40lbs lighter than the stock catback, which is what I said. Weigh your stock catback exhaust, and then weigh the Ti catback.

As far as RB stuff goes I like all of it, not my style personally, but it is all top notch stuff. I know quite a few guys down there and have nothing against them or their products. I wasn't saying that their stuff is worse than ours, or bad or even flawed in any way. I was simply saying that we are equal in quality and that at the level we are all operating it is a lot of times a matter of personal taste that deliniates which exhaust system a person is going to choose. The RB setup is an attractive package to be sure, but it isn't my cup of tea.

 

I'm not disagreeing with you on that, but most aftermarket single catbacks offer a similar weight saving, including your own all-SS catback. I can't understand why anyone would pay another $200 just to save 4lb. Is there some other advantage or difference I'm missing? Hell, I burn 4lb of gas just driving to work.

 

haha yeah i supose only a hardcore person would really want it, but hey it does look cool and sound scool to say u got TITANIAM exhaust!

 

I wish Greddy made their full Ti exhaust for FCs, damn the FD guys. I've seen those go for low as $400, Full Titanium weighs 11lbs!

 

Heh, like Kompressor said, you have to remember what kind of people our customer base is. A lot of these people really really really care about how the exhaust tip looks. They're not all the savvy individuals that all of you are. We had enough people email and call us and say "We want a titanium tipped exhaust!" that we decided to make them. Those people are the ones who buy it I'm sure.

I personally just run the standard SS one. No JDM tyte weight savings for me!

 

yeah i bought the SS one cause im cheap and it looks fine to me!

 

Have you guys tested the noise level increase from stock exhaust to your SS/Ti exhausts?


Not interested just curious.

 

haha ohh boi its A BIG diff, with at urbo its not to crazy loud, but if u try and rig up there 3" system to a NA with straight pipe its loud as hell!!

 

Like I said i'm not buying their exhaust I just want to have a ball part in my mind when I think of this setup.
